Sarcasm doesn’t travel well over text message — and I can say that through bitter experience. I’ve probably come close to being slapped, dumped, kicked in the crotch, fired, and/or run over by a riding mower because of some sarcastic text I’ve sent that was misconstrued as mean when it was supposed to be hilarious.

Or so I’ve imagined; I have no real gauge, because in each instance I couldn’t actually see the reaction on the face of the recipient. At least one of the developers behind React Messenger must have faced the same problem, because they’ve come up with a solution that snaps and sends a quick, expressive selfie along with each text.

Think your inbox is a dizzying mass of junkmail? The serial entrepreneur who started About.com wants to help you unclutter; not by getting rid of spam, which has been pretty much wiped out at this point — but by allowing you to group or unsubscribe from commercial emails with laser precision.

Keeping tabs on your brood this Halloween? Sure, you could use Apple’s Find My Friends. But it doesn’t have as many cool features as these two new apps, and it also can’t track Android phones — while these two apps can.

A year and a half ago, Bob Shor’s diabetic dad asked him if he had seen his dad take his insulin. Bob’s answer, “No, I didn’t see you take your meds” was interpreted by his father as “No, you haven’t taken them.” His dad overdosed that day, which Bob says was the reason he and his brother Rotem created MediSafe, a collaborative app that helps keep track of long-term medication.

The app will remind users when it’s time to take meds, and display dosage and an image of what the meds actually look like. There’s even a refill reminder and personalized information and details about taking the drug and effects. But the big feature is the app’s collaborative nature.

I remember a few tech bloggers going nuts over Vine when it hit the street back in January. I wasn’t convinced; it seemed too limiting, felt too gimmicky. Vine turned out to be a more creative tool than I’d imagined — at least for others. But the concept never really hooked me enough to want to use it.

Cameo, on the other hand, had my juices flowing almost immediately. Like Vine, Cameo shoots short, six-second HD (720p) clips that can be uploaded to Cameo’s website or shared via social media and email. Unlike Vine, multiple six second shots can be combined into a two-minute (maxiumum) clip, with light editing tools, effects and music added to the mix. And Cameo even lets you collaborate with friends.

Just as easy-to-use creative apps like iMovie and GarageBand have made it easier to craft music and videos, so AppSeed is poised to make it much easier to build iOS apps. Simply using the app to snap a photo of a rough sketch scribbled onto a notepad or napkin will turn that sketch into working, interactive interface pieces that can be arranged, re-arranged and tested.

Two of the versions are on sale till the end of the week: The most basic version, DataMan Next, is free (from a buck); and DataMan Pro is on sale at $5, which is half off its regular $10 price. The Pro version also now reports hourly data usage by app, which pretty much makes it the most detailed data-tracking app out there.

Just after CES wound down back in January, I was part of a (relatively) small group of journalists and bloggers present at the Disney media event that revealed Disney’s Infinity game universe to the world. Problem was, I had no clue why I’d been invited, as all the hoopla was about the console game. Toward the end, I bumped into Bill Roper, Disney’s product development chief, and asked why I was there as I gulped down a delicious, miniature milkshake.

His answer was cryptic. But the reason I’d been invited has just made its entrance onto the app store today — it’s the Disney Infinity: Toy Box iPad app, a virtual sandbox mashup that allows anyone with an iPad to take a variety of Disney characters and play with them in different Disney worlds. And it’s free — for now.

Here’s a problem: Let’s say you’re a diabolical dictator bent on world domination. You’ve decided to bypass the corporate mass media (which can’t be trusted) and inform the little people of your plans via podcast. You create one—only you don’t have a method of broadcasting the podcast, since you insist on personally playing your message directly onto the iDevices of your soon-to-be thralls.

The answer, of course, is the world-domination tool TuneMob. As long as you can gather everyone in the world into the same room. And by everyone, I mean a maximum of seven people. Who all need to be running TuneMob. And have fairly newish iDevices.
